Can we stop the retainer and come back later?

Stopping is a month-end decision and nothing more: no notice period, no exit fee, no unwinding, because the systems are built in your own licences and stay yours whether or not I am checking them. Restarting after a gap is welcome but honest: drift does not pause because the check did, so a return usually begins with a short reading of where the systems now stand, priced in writing like everything else, before the monthly rhythm picks back up. A gap of a month or two is usually trivial; after a year, with new people and changed tools, the reading matters more. None of that is a penalty for leaving. It is the same rule the whole practice runs on: I do not keep something honest without first knowing what it currently is.
